Module command 

Command building block for click-rs.

This module provides the Command struct, which is the basic building block of command-line interfaces in click-rs. A command handles argument parsing and invokes a callback function with the parsed values.

Reference

Based on Python Click’s core.py:Command class (line 873+).

Example

use click::command::Command;
use click::context::Context;
use click::option::ClickOption;
use click::argument::Argument;

let cmd = Command::new("greet")
    .help("Greet someone by name")
    .option(
        ClickOption::new(&["--name", "-n"])
            .help("Name to greet")
            .default("World")
            .build()
    )
    .argument(
        Argument::new("count")
            .help("Number of times to greet")
            .build()
    )
    .callback(|ctx| {
        // Access parsed values from ctx.params()
        Ok(())
    })
    .build();

assert_eq!(cmd.name, Some("greet".to_string()));
assert!(!cmd.hidden);
